Do you realize what these words mean when you hold the exact opposite?
I'm not the one who holds the exact opposite, I accept, echo and hold that their explanations
are as true today as they were then and always will be. Until you understand it as the popes have explained it, you
will have to really need to admit that their teachings on what the magisterium is are wrong (error), mistaken and erroneous - which actually *is* the exact opposite of what they teach.
For the OP, the Church's universal magisterium is
"all that has been handed down as divinely revealed by the ordinary teaching authority of the entire Church spread over the whole world, and which, for this reason, Catholic theologians, with a universal and constant consent, regard as being of the faith." - Pope Pius IX
It is necessary to remember that within the Church, the word "Universal" *always* includes the element of time, as in "since the time of the Apostles and till the end of time," iow, what the Church has taught and the faithful have believed always and everywhere, this is the simple definition of Church's universal magisterium.
